Let’s get started.

Introduction: When a Single Shot Changed Everything

Picture this: it's 1988, and polio is paralysing 1,000 children every single day across India. Families are terrified. Parents watch their children lose the ability to walk. The disease doesn't announce itself with warning signs—it just strikes, swift and devastating. For centuries, humanity had no answer. And then came the vaccine.

Fast forward to 2025, and India hasn't recorded a single case of polio in over three decades. Think about that for a moment. Not one. In a country with 1.4 billion people, with diverse climates, scattered rural villages, and countless logistical challenges, India achieved something that seemed impossible. This isn't luck. This is the power of life-saving vaccines, meticulous planning, and a nation-wide commitment to protecting its children.

Today, as new diseases emerge and vaccine hesitancy spreads misinformation across social media, understanding India's vaccine story has never been more important. Whether you're a parent deciding on your child's vaccinations, a traveller preparing for international travel, or simply someone curious about how public health actually works, this guide will walk you through everything you need to know about life-saving vaccines in 2025 and why India's polio victory matters to all of us.

What Are Life-Saving Vaccines, Really?

Let me start with the basics, because there's a lot of confusion out there, and I want to be clear from the beginning.

Life-saving vaccines are medicines designed to train your immune system to recognize and fight specific diseases before you ever encounter them naturally. They're not cures—they're preventives. And unlike most preventive measures that require constant effort, vaccines offer long-term, often lifelong protection with just one or a few doses.

Your immune system works like a defense force that protects your body from harmful invaders. Without a vaccine, your security team is walking around blindfolded when a dangerous intruder shows up. They have to figure out what they're fighting while being attacked. It's chaotic and often deadly. With a vaccine, your immune system gets a detailed photo of the intruder beforehand. It learns the face, the tactics, the weaknesses. When the real thing shows up, the security team recognises it immediately and neutralises it.

The term "life-saving" isn't hyperbole. We're talking about vaccines that prevent diseases like polio (which can cause permanent paralysis), measles (which kills), tetanus (which is often fatal), hepatitis B (which causes liver failure), and the flu (which kills thousands annually). These aren't minor infections—they're diseases that have killed hundreds of millions of people throughout human history.

What makes vaccines truly remarkable is their reach. They work for everyone, from newborns (with some vaccines) to elderly people. They work across socioeconomic classes. They're one of the most cost-effective health interventions ever developed—a few rupees' worth of vaccine prevents lifelong disability or death that would cost lakhs to treat (if treatment is even possible).

How Do Vaccines Actually Work to Save Lives?

This is where things get interesting, because understanding the mechanism helps dissolve a lot of vaccine myths floating around online.

Your immune system has two main branches: the innate immune system (your fast-response team) and the adaptive immune system (your precision strike force). Most diseases exploit the fact that your adaptive immune system takes time to recognize them. While your adaptive system is figuring things out, the disease is replicating, spreading, and causing damage.

Vaccines accelerate this recognition process. They show your adaptive immune system what the enemy looks like without actually causing the disease. Here's how different types work:

Live Attenuated Vaccines (like the original polio vaccine or MMR) use a weakened version of the actual virus. Your immune system sees the real thing, but in a form too weak to cause actual disease. It's like a training exercise with the actual opponent, but they're out of shape and tired.

Inactivated Vaccines (like hepatitis A or the flu shot) use a killed version of the pathogen. Your immune system learns the recognition signals without any risk of the disease taking hold. It's like learning from a detailed photograph.

Subunit Vaccines (like HPV vaccine) show your immune system only the key identifying parts of the pathogen—not the whole thing. It's like learning to recognize a person by their distinctive tattoo rather than needing to see their entire body.

mRNA Vaccines (like the COVID vaccine) give your cells the instructions to make a harmless version of a viral protein. Your immune system then responds to that. It's the most elegant system—your own cells become the training ground.

When vaccines work properly, your immune system produces antibodies (specialized proteins that identify and neutralize invaders) and memory cells that remember how to fight that specific disease for decades. Sometimes for life.

This is why vaccines are life-saving: they give your body the ability to fight diseases that would otherwise be either fatal or permanently disabling. There's no negotiation, no "maybe it won't be that bad." A vaccinated person encountering the actual disease is essentially already prepared for the fight.

Are Vaccines Safe for Children? The Evidence-Based Answer

This is the question I hear most often, and I understand why. Parents naturally want to protect their children, and when there's conflicting information online, it's hard to know what to trust.

Here's what the data shows: vaccines are extraordinarily safe, especially for children. I'm not saying this based on someone's opinion or a social media post. I'm saying this based on decades of data from billions of doses administered globally, including in India.

The Universal Immunisation Programme (UIP) in India has given over 2 billion vaccine doses since its inception. Serious adverse events occur in roughly 1-2 per million doses. To put that in perspective, the actual disease that the vaccine prevents has a death rate measured in percentages for children. The polio virus paralysed hundreds of thousands of Indian children annually before the vaccine. The polio vaccine has caused severe complications in approximately zero children across the 30+ years India has been using it.

Compare the risk profiles: getting the measles vaccine has a severe side effect rate of about 1 per million doses. Getting actual measles has a death rate of about 1-2 per 1,000 infected children in India. The math is not close—the vaccine is vastly safer.

The safety monitoring systems in place are rigorous. Every vaccine batch is tested before release. Adverse events are reported and tracked through formal systems like Vigibase (the WHO's global database). If problems are detected, action is taken immediately. The system isn't perfect, but it's orders of magnitude better than the alternative—letting preventable diseases freely circulate.

Different vaccines carry different common side effects, and it's actually good to know what to expect:

Mild soreness or swelling at the injection site happens with most vaccines
Low-grade fever is common, especially after live vaccines like MMR
Temporary irritability or fussiness sometimes follows vaccination
Very rare serious reactions like severe allergic reactions occur in about 1-2 per million doses, often in people with known allergies

The serious side effects typically appear within minutes to hours of vaccination, which is why health providers ask you to wait for 15-30 minutes after vaccination. If a reaction occurs, medical staff is right there.

What doesn't happen? Autism. Diabetes. Asthma. Allergies. These claims have been investigated exhaustively, and no causal link exists. The original study claiming vaccines cause autism was fraudulent—the author lost his medical license. But the myth persists online, which tells you something important: misinformation spreads faster than truth. Being aware of this helps you navigate the information landscape critically.

What Are Common Side Effects? What's Normal vs. What's Not

Since we're talking about safety, let's be specific about what to expect and when to be concerned.

Normal side effects (these are expected and typically resolve within 24-48 hours):

Soreness, redness, or slight swelling where the needle went in
Low-grade fever (up to 100.4°F or 38°C)
Mild tiredness or fussiness, especially in children
Mild body aches or headache
Loss of appetite for a meal or two

None of these require medical intervention—they're your immune system doing exactly what it's supposed to do. Rest, fluids, and perhaps acetaminophen (for fever, following dosage for age) is all that's needed.

When to seek medical attention (these are rare but possible):

High fever (above 101°F or 38.3°C)
Difficulty breathing
Severe swelling of face or throat
Rash that looks unusual or spreads rapidly
Difficulty moving a limb
Seizures

If any of these occur, go to your nearest medical facility. Document the timing relative to vaccination. These reactions are rare enough that they're typically monitored closely, and in most cases, they resolve without long-term complications.

The importance of reporting: In India, adverse events post-vaccination should be reported to your local ANM (Auxiliary Nurse Midwife) or at the nearest health centre. These reports go into the national database and help identify patterns or problems. Your report matters.

The Polio Vaccine Myth That Won't Die: Vaccines Don't Cause Autism

I'm going to address this head-on because it's the most persistent vaccine myth, it causes real harm to public health, and it deserves a thorough debunking.

In 1998, a British doctor named Andrew Wakefield published a study in The Lancet claiming that the MMR vaccine caused autism. The study was based on just 12 children, had obvious methodological flaws, and—this is crucial—was later revealed to be fraudulent. Wakefield had financial conflicts of interest, had manipulated data, and had lost his medical license by 2010.

Despite this, the myth spread. Parents started refusing vaccines. Measles outbreaks occurred. Children died. And yet, the myth persists.

Here's what decades of subsequent research actually show: there is no link between vaccines and autism. Studies involving hundreds of thousands of children have found no connection. The autism diagnosis rates have risen, yes, but this is due to better screening and broader diagnostic criteria, not vaccines. Autism is detectable before vaccination occurs. Countries with high vaccination rates and countries with low vaccination rates have similar autism rates.

The most important thing I can tell you is this: don't let this one debunked study determine your child's health. Polio is real. Measles is real. And they can kill. Autism is also real, and it deserves support and acceptance—but vaccines aren't the cause.

Following a Vaccine Schedule: Why Timing Matters

You've probably seen the Indian vaccination schedule, and it looks complicated. There are ages, different vaccines, sometimes boosters. It can feel overwhelming. But this structure exists for deeply scientific reasons.

The vaccine schedule is designed around your immune system's development. Your immune system isn't fully mature at birth. Different components develop at different stages. The schedule times each vaccine for when your body will mount the most effective response.

For example, newborns get hepatitis B vaccine at birth because they're most vulnerable then. The polio vaccine series starts at 6 weeks because that's when your immune system is developed enough to respond effectively to inactivated polio vaccine. The MMR vaccine isn't given until 9 months (or 12 months depending on situation) because antibodies from the mother interfere with live vaccines before that age.

Boosters exist because immunity can wane over time. Your body doesn't maintain perfect antibody levels forever. A booster dose "reminds" your immune system, revving up protection. This is why you get DPT boosters at school age and tetanus boosters every 10 years in adulthood.

Deviating from the schedule reduces protection. If you skip doses, your child isn't fully protected. If you space doses too far apart, your body might not mount an effective response. Your healthcare provider isn't being unnecessarily rigid—they're following a protocol designed by public health experts to maximize your protection.

When Is the Polio Vaccine Given? India's Specific Schedule

Let me give you India's exact polio vaccination timeline, because this is crucial for understanding India's polio-free status.

The India UIP Polio Schedule looks like this:

Birth to 6 weeks: IPV (Inactivated Polio Vaccine) - first dose
10 weeks: IPV - second dose
14 weeks: IPV - third dose
6-12 months: OPV (Oral Polio Vaccine) - 1 dose
12-23 months: OPV - 1 dose
16-24 months: IPV - booster
School entry (5-6 years): OPV booster

Wait, what's the difference between IPV and OPV? I'm glad you're wondering.

IPV (Inactivated Polio Vaccine) is an injection containing killed poliovirus. It's what the vast majority of countries use now, including India's primary program. It's safe, effective, and you don't risk transmitting the vaccine virus to others.

OPV (Oral Polio Vaccine) is a drop you swallow containing a live but weakened poliovirus. It's cheaper and creates intestinal immunity (blocking transmission), which is why it was historically important for polio eradication. India still uses it in select scenarios because the extra intestinal immunity helps maintain the polio-free status and prevents any wild-type virus from establishing itself.

India's strategy is sophisticated: IPV for primary protection (safe for all, especially immunocompromised children), and OPV pulses during Polio Immunization Days (PIDs) to maintain population-level protection. This combination is why India went from hundreds of thousands of cases annually to zero.

What Vaccines Are Required for School? Legal Requirements in India

If you have a child starting school, you'll encounter vaccine requirements. These exist to protect all children, not just the vaccinated ones.

India doesn't technically have a legal mandate for school vaccines in the way some countries do, but most schools require proof of UIP vaccination or at minimum, vaccinations against:

DPT (Diphtheria, Pertussis, Tetanus)
Polio
Measles/MMR
Hepatitis B (increasingly common)

Some private schools are stricter and require additional vaccines beyond the UIP schedule. International schools often follow WHO guidelines, which include more extensive immunizations.

The reason schools care isn't because they're being difficult. It's because schools are high-transmission environments. If even one unvaccinated child brings measles into school, it spreads rapidly to other unvaccinated children. Vaccinated children are protected, but vulnerable infants (too young for vaccination) and severely immunocompromised individuals (unable to be vaccinated) become at risk.

Depending on the disease, herd immunity generally needs 85–95% of the population to be vaccinated. At that level, diseases can't spread widely enough to infect the remaining unvaccinated individuals. It's a collective shield, and schools are one of the key places this matters.

Document your vaccination records and keep them safe. You'll need them for school admission, sometimes for college, and potentially for international travel.

Can Vaccines Cause Serious Long-Term Harm? Separating Fact From Fear

This is a genuine question that deserves a serious answer, not dismissal.

The short answer: no, vaccines don't cause serious long-term harm in any way that would be tolerable compared to the diseases they prevent.

Let me explain why I'm so confident. Vaccines work quickly and then are cleared from your body. Your immune system responds, produces antibodies and memory cells, and then the vaccine itself is metabolized and excreted. It's not hanging around in your system causing delayed problems.

The longest safety data we have on vaccines is for vaccines introduced decades ago. First introduced in the 1950s, the polio vaccine has been used worldwide for decades. The MMR vaccine since the 1970s. We have literally billions of doses of data. If serious long-term side effects were occurring, we would see them by now. We don't.

What we do see is people living into their 80s and 90s, having been vaccinated as children, with no long-term health consequences attributable to vaccines.

Now, could a rare individual have a delayed reaction? Theoretically, anything is possible. But delayed serious reactions are extraordinarily rare compared to:

Immediate side effects from the disease itself (polio causing lifelong paralysis, measles causing deafness, HPV causing cancer)
Long-term complications from the disease (survivors of polio reporting post-polio syndrome decades later, people who survived measles having permanent hearing loss)

The risk-benefit calculation is stark. You're comparing essentially zero documented long-term vaccine harm against well-documented, high-frequency long-term disease harm. The math doesn't support avoiding vaccines out of concern for long-term effects.

Are Boosters Necessary? When and Why They Matter

Boosters are doses given months or years after initial vaccination to refresh immunity. The question is reasonable: if the vaccine worked, why do we need more?

The answer is biology. Antibody levels naturally decline over time. It's not a design flaw—it's actually efficient. Your body doesn't need to maintain armies of antibodies for diseases you're not currently fighting. But if you encounter the actual disease, you want that protection.

A booster works like a refresher course. It re-exposes your immune system to the pathogen (or a part of it), reminding your body how to fight it. Your immune response is often faster and stronger the second time around because your immune system has memory.

Which vaccines need boosters?

Tetanus: Every 10 years for adults (or after injury if it's been more than 5 years)
Pertussis: Boosters incorporated into Tdap for adolescents and adults
Polio: Some schedules include boosters, some don't—depends on risk factors
Hepatitis B: Some people need boosters; depends on antibody levels
MMR: Typically one dose of MMR provides lifetime immunity; boosters not usually needed
Shingles: Two doses (shingles vaccine is newer, so booster data is still emerging)

The simple rule: if your healthcare provider recommends a booster, it's because protection is declining and you're at risk. Follow their recommendation.

What Vaccines Do Adults Need? You're Not Done After Childhood

One of the biggest mistakes adults make is assuming they're done with vaccines. Not true.

All adults should have:

Tetanus: Booster every 10 years (often combined with diphtheria and pertussis as Tdap)
Influenza: Annual flu shot
COVID-19: Based on current guidance (boosters as recommended)

Adults should consider:

MMR: If you weren't vaccinated as a child or don't have immunity
Hepatitis A: If you travel internationally or have specific risk factors
Hepatitis B: If you work in healthcare, have multiple partners, or travel internationally
Shingles: Adults over 50 are increasingly being offered this
HPV: Adults up to age 45 (especially those with multiple partners or higher risk)
Pneumococcal: Adults over 60 or with chronic conditions

Travellers need specific vaccines:

If you’re traveling to parts of Africa or South America, yellow fever vaccination may be required.
Japanese Encephalitis: If travelling to endemic areas in Asia
Typhoid: For travel to South Asia, including India (if you're coming from a non-endemic country)
Meningococcal: For some regions, especially sub-Saharan Africa

The point is, vaccination isn't just for children. Your immunity status matters throughout your life. If you're unsure what you need, a simple conversation with your doctor or visiting a travel clinic can clarify.

How Effective Are Life-Saving Vaccines? The Numbers

Vaccine effectiveness is measured in percentages representing how much the vaccine reduces the risk of disease compared to unvaccinated people.

The headline numbers:

Polio vaccine (IPV): 99% effective with 3 doses
MMR vaccine (measles): 97% effective with 2 doses
Tetanus vaccine: 95% effective
Hepatitis B vaccine: 95% effective
Influenza vaccine: 40-60% effective (varies yearly; lower than other vaccines but still significant)
HPV vaccine: 99% effective against targeted strains when given before exposure
COVID-19 vaccines: 70-95% effective against severe disease (varies by variant and vaccine type)

Notice the pattern? Life-saving vaccines work. They work really well.

But what does "95% effective" actually mean? This indicates that when a vaccinated population is exposed to the disease, approximately 95% remain protected. The remaining 5% might still get infected, but usually with milder symptoms. It's not 100% protection, but it's close to it for most vaccines.

Compare this to no vaccine: 0% effective. Everyone exposed gets infected (unless they're naturally immune from prior infection, which is far riskier).

Vaccine effectiveness varies with:

Age: Older adults sometimes have weaker responses
Immune status: Immunocompromised individuals may not respond well
Time since vaccination: Protection wanes over years, which is why boosters exist
Viral mutations: For rapidly changing viruses like influenza, new strains emerge faster than vaccines can target them

The point: vaccines work. They're not perfect, but they're remarkably effective. A 95% effective vaccine preventing a disease with a 10% mortality rate is an incredible trade-off.

India's Polio Victory: How a Nation Conquered a Killer

Now let's talk about what makes India's polio story remarkable, because it's genuinely one of the greatest public health achievements in human history.

The situation in 1988: India recorded 100,000 polio cases annually. Entire villages dealt with paralysed children. Parents lived in terror. The disease showed no mercy—rich or poor, urban or rural, educated or illiterate, polio struck anyone who wasn't vaccinated.

The obstacles were staggering:

Infrastructure: India had villages without roads, let alone health facilities
Population: 800+ million people spread across a vast territory
Literacy: Many parents didn't understand vaccines
Misinformation: Rumours about vaccines were common
Weak health systems: Rural India had minimal healthcare infrastructure
Logistics: Getting vaccines to remote areas and keeping them cold was extremely difficult

The solution involved:

Pulse Polio campaigns starting in 1995, where health workers went door-to-door vaccinating every child under 5 with OPV. Not just in clinics, but in homes, streets, markets.

Surveillance system: Training ANMs and health workers to detect and report suspected polio cases immediately. Every child with sudden paralysis was investigated.

High-risk area focus: Identifying districts with poor coverage and directing extra resources there.

Community mobilisation: Getting religious leaders, teachers, and local influencers to promote vaccination.

Political commitment: Multiple governments maintained focus on this single goal across decades.

Integration with existing programs: Linking polio to routine immunisation and using the same health worker network.

The results speak for themselves:

1989: 100,000 cases
1995: Still 60,000 cases (when Pulse Polio started)
2000: 265 cases
2005: 66 cases
2010: 0 cases (last case in October 2010)
2025: Still zero cases

India is now one of 47 polio-free countries. The last case in the entire Asian region occurred in Afghanistan in 2018. India's achievement required vaccinating billions of children and maintaining a 99%+ coverage rate for years.

The Vaccine Schedule Question Everyone Asks: Can I Change the Schedule?

Parents sometimes ask if they can delay vaccines, space them differently, or follow an alternative schedule. I understand the impulse—you want to feel like you're making informed decisions about your child's care.

Here's the reality: the vaccine schedule is based on science, not convenience.

The timing of vaccines corresponds to:

When your child's immune system can respond effectively
When your child is most vulnerable to the disease
When maternal antibodies won't interfere
When the gap between doses provides optimal immune response

Changing the schedule doesn't make vaccines safer; it actually delays protection during your child's most vulnerable period. A child vaccinated late against measles is unprotected and vulnerable to measles during the delay.

What you can do: If your child is sick (seriously ill, not just mild cold), vaccination can be delayed slightly. Discuss specific concerns with your paediatrician—they know your child's situation and can advise accordingly. But wholesale rejection or major delays of the schedule is a decision to leave your child unprotected during vulnerable times.

The good news? If you've already delayed some vaccines, it's never too late to catch up. Your paediatrician can help create a catch-up schedule.

Common Questions Parents Ask About Vaccines

Q: Are vaccines sterile? Yes. Every syringe and needle used in vaccination in authorized clinics is sterile. This is verified during procurement and storage.

Q: Can my child get the disease from the vaccine? With live vaccines (like OPV or MMR), there's a theoretical tiny risk, but the vaccine virus is extremely weakened. With inactivated vaccines (like IPV or hepatitis B), the pathogen is dead—you cannot get the disease from the vaccine.

Q: How long do vaccines take to work? It depends. Some protection starts immediately. Full immunity usually develops within 1-2 weeks for inactivated vaccines, sometimes longer for live vaccines. This is why vaccination before travel is important—you need time for immunity to develop.

Q: What if I can't afford vaccines? All UIP vaccines are free at government health facilities. If you're going to a private facility, discuss costs—many offer financial assistance or vaccine drives.

Q: Can I get multiple vaccines at once? Yes. Modern vaccines are designed to be given together. Spacing vaccines weeks apart doesn't make them safer; it delays protection.

Q: What if I lose my vaccination record? You can get re-vaccinated. It's not dangerous to get a vaccine you've already had. Some blood tests can check for immunity if you're concerned.

Why Polio Freedom Matters Beyond Just Polio

Polio eradication is important for reasons beyond just preventing polio itself.

First, it proves eradication is possible. Smallpox was eradicated through vaccination. Polio is nearly eradicated. This gives hope that other diseases might be eradicable too. If we can get there globally, other deadly diseases might follow.

Second, the infrastructure created for polio helps everything else. The surveillance system, the health worker network, the vaccine distribution system—all built for polio—now serves routine immunisation, disease surveillance, and public health emergencies. COVID-19 vaccination in India used infrastructure originally built for polio.

Third, it shows what coordinated global effort achieves. Polio eradication required governments, NGOs, healthcare workers, and communities across countries working together. It's proof that humanity can solve massive health problems when we commit to it.

Fourth, it protects the most vulnerable. Vaccination is how we protect people who can't be vaccinated—immunocompromised children, newborns too young for certain vaccines, pregnant women. When everyone else is vaccinated, these vulnerable populations benefit from herd immunity.

The Future of Vaccines: What's Coming in 2025 and Beyond

Vaccine development hasn't stopped. Scientists are working on vaccines for diseases we don't yet have solutions for.

In development or recently approved:

RSV vaccine: For respiratory syncytial virus, a leading cause of infant hospitalisation
Dengue vaccine: With improved efficacy; dengue is a massive burden in tropical countries like India Read more..
Malaria vaccine: Effective vaccines are finally emerging after decades of effort
Updated COVID boosters: Targeting new variants
Pan-coronavirus vaccine: A theoretical vaccine protecting against multiple coronavirus types
Cancer vaccines: Early-stage work on vaccines that help fight certain cancers

The vaccine technology that enabled rapid COVID-19 vaccine development (especially mRNA technology) is now being applied to other diseases. The future likely includes:

Faster vaccine development: We can develop vaccines in months instead of years
Better vaccines: More effective, fewer side effects
Combination vaccines: Multiple vaccines in one shot, reducing visits
Needle-free delivery: Patches, nasal sprays
Universal vaccines: Single vaccines protecting against multiple strains of a virus

Making Your Decision: A Practical Guide for Parents

If you're reading this as a parent trying to decide about vaccines, I want to give you clarity.

The data is unambiguous: Vaccinated children are healthier, have fewer serious infections, and suffer fewer complications than unvaccinated children. This isn't opinion—it's what the data consistently shows.

Specific steps for you:

Talk to your paediatrician. They know your child's medical history and can address your specific concerns. Bring questions.
Read from credible sources. Check CDC, WHO, or your government's health ministry website. Skip blogs and social media posts claiming to have secret information.
Understand the risks you're comparing. Compare the rare side effect risk of a vaccine against the real risk of the disease. The disease is almost always more dangerous.
Vaccinate on schedule. Delays increase the window your child is unprotected.
Keep records. You'll need them for school and travel.
Watch for side effects. Learn what reactions are normal and when you should consult a doctor.

If you've been hesitant, I want you to know that nothing is served by guilt. What matters is where you go from here. If your child is unvaccinated, catching up on vaccines is a positive step you can take today.

India's Polio-Free Future: What It Takes to Stay That Way

Maintaining polio-free status requires constant vigilance. One slip—allowing immunisation coverage to drop, allowing the vaccine system to weaken, allowing misinformation to spread—could restart the cycle.

What India does to maintain polio freedom:

Routine immunisation: Keeping vaccination coverage above 90% in every district
Surveillance: Active case searching for any paralysis cases
Rapid response: If polio is suspected, rapid testing and contact tracing
Border monitoring: Watching for any polio cases in neighbouring countries
Political commitment: Maintaining funding and focus across governments
Public trust: Educating parents about the vaccine

The infrastructure is strong now. The healthcare system is better. But it requires ongoing commitment. Polio could return if these efforts were abandoned.

This is why vaccine hesitancy matters. When parents refuse vaccines, they're not just making a personal choice—they're potentially creating pockets of vulnerability where a virus could re-establish itself and spread.

The Bottom Line: Life-Saving Vaccines in 2025

Here's what I want you to take away from this:

Life-saving vaccines are one of humanity's greatest achievements. They've saved more lives than any medicine, surgery, or public health intervention. Polio vaccination alone has prevented an estimated 18 million cases of paralysis.

India's polio-free status is no accident. It's the result of deliberate choice, enormous effort, and sustained commitment. It's something Indians should be proud of—and something we need to protect by maintaining vaccination rates.

Vaccine safety is serious and monitored. The rare side effects are always less dangerous than the diseases vaccines prevent. The systems in place to detect and respond to safety issues are robust.

Vaccines work. Measles, tetanus, polio, hepatitis B—these diseases are rare in vaccinated populations and devastating in unvaccinated ones. That's not coincidence.

Your vaccination decisions matter. Whether you're vaccinating a child, protecting yourself as an adult, or ensuring you have immunity before travel, these choices ripple through your family and community.

The simple fact is this: we live in a time where preventable diseases like polio are preventable. That's not a given. That's an achievement. That's something to protect.

If you take nothing else from this article, take this: India's polio-free victory isn't about one vaccine or one campaign. It's about a nation choosing to protect its children, systematically, consistently, with science and compassion. That same choice is available to you, for your family, right now.

Your Next Steps

Don't let this information sit. Take action:

Check your vaccination records. Know what you've had and what you might need.
Schedule a vaccination appointment if you or your children are due. Contact your nearest health centre or clinic.
Talk to your healthcare provider about any concerns. They're there to help, not judge.
Share this with someone who might be vaccine-hesitant. Sometimes credible information makes the difference.
Celebrate the achievement. Tell someone that India has been polio-free for over three decades. It's worth celebrating.

Your health is your responsibility. Vaccination is one of the most important responsibilities you can take seriously.
